The site of a post-medieval spinning mill. Local history records that James and Edward Moore established a sailcloth-manufacturing business in 1790, initially operating from Duke Street, Douglas, and renting Ballabeg farm in Braddan. After the brothers' partnership was dissolved in 1814, Edward Moore relocated operations across the river to Tromode. In the 1840s, Edward's nephew William Fine Moore developed a flax mill on the site, powered by a 19-foot-diameter iron water-wheel supplemented by a steam engine in low water, processing flax through heckling, roving, spinning and weaving. The sailcloth and flax works continued until 1905, after which the site was used by other businesses including a laundry and a brush factory.
